Toffset (internal loop delay) of CPRI IP

Jump to solution

Hello,

I am changing the timing of tx strobe against rx strobe from the CPRI master. Can this affect the internal loop delay within the CPRI IP?

Thanks!

Hi @namsh ,

Tx strobe should be generated as per the Timing diagram show in the PG056 figure no 3-46. Based on the nodebfn_tx_strobe the data is aligned and transmitted as per CPRI protocol . I believe It will not change the internal Loop delay as  all the components in data path remain  same.

Thanks,
